BBF Factory Edition — Structured Rubber Strap
BBF Factory’s iteration of the 42mm Big Bang Unico King Gold Pave (441.OX.1181.RX.1104) stands as a significant technical benchmark in modern horological replication. By engineering a bespoke movement rather than relying on standard modified ETA-7750 bases, BBF achieves a highly accurate structural replication of the genuine UNICO architecture, allowing for proper subdial spacing and functional integrity.
At the core is the custom HUB1280 super clone caliber. Unlike standard chronograph replicas that are limited to a 30-minute counter, this movement features a full 60-minute tracking subdial at 3 o’clock and a true flyback function, permitting instantaneous reset without stopping the mechanism. The visible column wheel mechanism at 6 o’clock interacts accurately with the pusher actuation, providing a mechanically satisfying tactile response.
The 42mm case is constructed from 316L stainless steel heavily plated in Hublot’s proprietary King Gold hue, paired with a meticulously set pave diamond replica bezel. Measuring at a verified 15.4mm thickness and weighing 180.4g, it maintains a substantial wrist presence while the matte black skeletonized dial reveals the intricate date wheel mechanism beneath.
- Movement: Custom HUB1280 Flyback Clone — Approximately 36 hours
- Case Material: 316L Stainless Steel with 18K King Gold Plating, 42mm diameter, 180.4g weight
- Bezel: Pave Synthetic Diamond Set, accurate King Gold tone matching

This piece caters to collectors seeking the mechanical complexity of a flyback chronograph combined with high-impact aesthetics. The 42mm profile ensures better wearability than the traditional 45mm Big Bang models, though the diamond-set bezel dictates a highly specific wearing scenario.
